[0054] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0055] Figure 1 This is a flowchart of the steps of a display control method provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method may include:

[0056] Step 101: Configure the mode of the first bus interface of the specified chip in the control terminal, and map the video memory space of the specified chip through the server; the control terminal and the server are connected through the first bus interface, which is used for the server to access the video memory space.

[0057] Step 102: Read the data to be displayed from the video memory space of the specified chip; wherein, the data to be displayed is the data that the server connected to the control terminal needs to display.

[0058] With the continuous development of technology, some system-on-a-chip (SoC) has display functionality, and can be used not only as a control chip but also as a graphics card. In this embodiment of the invention, the designated chip can be a chip that simultaneously possesses independent display functionality; that is, the designated chip can have both control and independent display functions. The specific model of the designated chip can be selected according to actual needs, as long as it ensures that the designated chip has both control and independent display functions.

[0059] In this embodiment of the invention, the method can be applied to the control end. Configuring the mode of the first bus interface and mapping the video memory space of the specified chip to the server can be considered as setting up the specified chip as a graphics card, thereby allowing the data to be displayed to be written into the video memory space of the specified chip and used as a graphics card. In this embodiment of the invention, the control end and the server can also be connected through the second bus interface of the specified chip. The second bus interface is used for the control end to send control commands to the server, such as restart commands, shutdown commands, application installation commands, etc. For example, the control end can generate control commands according to actual needs and then send the control commands to the server through the second bus interface. In this scenario, the server can be considered the controlled end. In this way, while implementing control functions for the server based on the specified chip, the display functions provided by the specified chip can be further utilized to display the data to be displayed by the server based on the video memory space of the specified chip, thereby improving the chip utilization rate of the control end.

[0060] Furthermore, the specific device types of the control terminal and server can be set according to actual needs, and this embodiment of the invention does not impose any restrictions on this. Furthermore, the control terminal can be connected to the server via a first bus interface and a second bus interface of a designated chip. The first bus interface can be used for the server to access the video memory space. This ensures that the control terminal can display the data to be displayed by the server while simultaneously controlling the server normally; that is, the designated chip is used as both the control chip and the server's graphics card for data display. The data to be displayed can be written by the server, and the specific type of data to be displayed can be set according to actual needs; this embodiment of the invention does not impose any restrictions on this. For example, the data to be displayed may include related data stored in the server, server device parameters, such as CPU utilization, memory utilization, CPU temperature, continuous running time, etc. This allows users to easily understand the server's status based on the displayed data.

[0061] Step 103: Display the data to be displayed on the screen based on the specified chip.

[0062] The display screen can be connected to a control terminal. The control terminal displays the data to be displayed based on a designated chip, essentially using the designated chip as a dedicated graphics card for the server to achieve the display function. In this way, by reusing the display function provided by the designated chip to display the data to be displayed by the server, the server's graphics card resources can be saved to some extent.

[0063] In summary, the display control method provided by this invention configures the mode of the first bus interface of a specified chip in the control terminal and maps the video memory space of the specified chip through a server. The control terminal and the server are connected through the first bus interface, which is used by the server to access the video memory space. Data to be displayed is read from the video memory space of the specified chip; wherein, the data to be displayed is the data required to be displayed by the server connected to the control terminal. The data to be displayed is displayed on the screen based on the specified chip. Thus, through configuration and mapping operations, the data to be displayed by the server can be written into the video memory space of the specified chip, using the specified chip as a graphics card. Based on the video memory space of the specified chip, the data to be displayed by the server is displayed, thereby improving the chip utilization rate of the control terminal.

[0064] Optionally, in this embodiment of the invention, step 101 may specifically include:

[0065] Step 1011: Configure the first bus interface to a specified mode.

[0066] Accordingly, when the first bus interface is configured in a specified mode, the server will identify the control terminal connected based on the first bus interface as an external device and allocate a first bus domain to the control terminal.

[0067] After allocating the first bus domain to the control terminal, the server writes the data to be displayed based on the space address corresponding to the allocated first bus domain. Specifically, the server can write the data to be displayed to the space address corresponding to the first bus domain. Correspondingly, the control terminal can receive the data to be displayed written by the server based on the space address corresponding to the first bus domain.

[0068] The specified mode can be a mode that enables the control terminal to be recognized as an external device. For example, the first bus interface can be a high-speed serial computer extended bus standard (Public Component Interconnect Express, PCIe) bus interface. The first bus interface can support master and slave modes, and the specified mode can be slave mode. This ensures that after configuration, the server can recognize the control terminal connected via the PCIe bus interface as a PCIe device, and the control terminal can act as a graphics card device to display information output by the server. Specifically, mode configuration can be performed during the initialization of the specified chip to configure the first bus interface of the specified chip as slave mode (EP mode). For example, the value of the corresponding register can be configured during initialization to configure the first bus interface of the specified chip as slave mode. Further, after the server recognizes the control terminal as a PCIe device, it will allocate a PCIe bus domain for the PCIe device. Specifically, this can be by allocating the address space of the PCIe device within the PCIe bus domain. This address space can correspond to a block of memory. The server can write the data to be displayed based on the address space corresponding to the first bus domain, i.e., the address of that address space.

[0069] In other embodiments, when the control terminal remotely controls the server, and the control terminal and server are connected via a first bus interface, the control terminal transmits instructions to a wireless module installed in the control terminal through the first bus interface. The wireless module then uses the wireless network to interact with the server. After recognizing the control terminal as an external device, the server allocates a first bus domain to the control terminal via the wireless network and sends the data to be displayed. Correspondingly, after receiving the data to be displayed through the wireless module, the control terminal writes the data to be displayed through the first bus interface based on the spatial address corresponding to the first bus domain.

[0070] Step 1012: Configure routing according to the space address corresponding to the first bus domain to map the space address to the address of the video memory space.

[0071] Specifically, the operation of the server mapping the video memory space of the specified chip can be to map the space address corresponding to the first bus domain allocated by the server to the address of the video memory space.

[0072] After allocating the first bus domain, the server can return the corresponding space address to the control terminal for routing configuration. Alternatively, the server and the control terminal may pre-agree on the space address corresponding to the first bus domain to be allocated to the control terminal for routing configuration; this embodiment of the invention does not impose any restrictions on this.

[0073] In this embodiment of the invention, by configuring the first bus interface to a specified mode, the server identifies the control terminal connected via the first bus interface as an external device and allocates a first bus domain to the control terminal. Routing is then configured based on the spatial address corresponding to the first bus domain to map the spatial address to an address in the video memory space. Since the server writes the data to be displayed based on the spatial address corresponding to the first bus domain, this embodiment maps the spatial address to an address in the video memory space of the control terminal. This ensures that when the server writes data to be displayed based on the spatial address corresponding to the first bus domain, the data to be displayed is written to the video memory space of the control terminal, thereby improving processing efficiency to some extent.

[0074] Optionally, in this embodiment of the invention, the following steps may also be performed:

[0075] Step 201: In the initialization phase of the specified chip, configure the target space size corresponding to the specified chip.

[0076] Specifically, the designated chip may include a Display Controller (DC) to implement independent display functions. During the initialization phase, the DC can be configured with a target memory size to allocate video memory. The target memory size is the size of the allocated video memory, which can be pre-specified based on actual needs. It should be noted that during the initialization phase, the operation of configuring the first bus interface to a specified mode can be performed sequentially or simultaneously with the operation of configuring the target memory size; this embodiment of the invention does not impose any restrictions on this.

[0077] Step 202: Send representation information to the server to represent the target space size, so that the server allocates a first bus domain of a corresponding size to the control terminal connected to the first bus interface based on the target space size represented by the representation information.

[0078] In this step, the characterization information can be a numerical value of the target space size. By sending the characterization information to the server, the server can know the actual size of the video memory space in the specified chip. Thus, after scanning the control terminal, that is, after recognizing the control terminal as an external device, it can allocate a first bus domain of the corresponding size to it, that is, allocate an address space of the corresponding size.

[0079] In this embodiment of the invention, the target space size corresponding to the specified chip is configured during the initialization phase of the specified chip. Characterization information representing the target space size is sent to the server, enabling the server to allocate a first bus domain of the corresponding size to the control terminal connected to the first bus interface based on the target space size represented by the characterization information. This ensures that the size of the address space allocated by the server is consistent with the size of the video memory space provided by the server, avoiding the inability to correctly write the required display data to the video memory due to size inconsistencies, thus preventing write operation errors.

[0080] Optionally, embodiments of the present invention may further include:

[0081] Step 301: Configure the routing of the specified register of the control terminal according to the space address to associate the space address with the specified address; the storage space corresponding to the specified address is used to cache the data to be displayed.

[0082] The designated register can be pre-set; for example, it is a register in the control terminal used to implement the PCIe controller. The designated address can be a pre-configured routing address according to actual needs, and this embodiment of the invention does not impose any restrictions on this. For example, an address that will not be used by other operations can be selected as the designated address to avoid operational conflicts. Specifically, code for routing the spatial address to the designated address can be configured in the designated register to associate the spatial address with the designated address. The operation of associating the spatial address with the designated address can be a routing configuration operation. By associating the spatial address with the designated address, when the server writes data to be displayed based on the spatial address, the data to be displayed will be written to the storage space corresponding to the designated address, and the data to be displayed will be cached based on the storage space corresponding to the designated address.

[0083] Accordingly, the operation of configuring routing based on the spatial address corresponding to the first bus domain to map the spatial address to the address of the video memory space can specifically include:

[0084] Step 302: If the specified address is found to be consistent with the address of the video memory space, the specified address is mapped to the address of the video memory space.

[0085] Specifically, the address of the video memory space can be obtained, and then compared with a specified address to determine if the specified address matches the address of the video memory space. If the specified address matches the address of the video memory space, it means that the storage space corresponding to the specified address is the video memory space. By simply configuring the routing, it can be ensured that when the server writes data to be displayed using the space address corresponding to the first bus domain, the data to be displayed is written to the video memory space.

[0086] Conversely, if the specified address and the address in the video memory space are inconsistent, it indicates that routing configuration alone will cause the server to write the data to be displayed to the memory space corresponding to the first bus domain, but the data to be displayed will be written to the memory space corresponding to the specified address. Therefore, this step can be further performed. Specifically, a mapping relationship between the specified address and the address in the video memory space can be established, thereby mapping the specified address to the address in the video memory space.

[0087] For example, Figure 2 This is a configuration initialization flowchart provided by an embodiment of the present invention, such as... Figure 2 As shown, the first bus interface can be configured to a specified mode first, enabling the server to identify the control terminal during initialization, thereby ensuring that a first bus domain is allocated to the identified control terminal. Next, the target space size corresponding to the specified chip can be configured so that the server allocates a first bus domain of the corresponding size to the control terminal connected to the first bus interface after scanning for the control terminal.

[0088] Furthermore, routing configuration can be performed based on the spatial address corresponding to the first bus domain to map the spatial address of the first bus domain to the address of the video memory space, enabling the server to access the video memory space of the control terminal through the allocated spatial address corresponding to the first bus domain. This initialization configuration includes: configuring the first bus interface to a specified mode, configuring the target space size, and configuring routing based on the spatial address corresponding to the first bus domain. After initialization is completed by the initialization function of the specified chip, the server can recognize the control terminal as an external device and allocate the first bus domain to the control terminal, since the spatial address corresponding to the first bus domain is mapped to the address of the video memory space. When the server writes data to be displayed to the spatial address corresponding to the first bus domain, it can directly write the data to be displayed into the video memory space of the control terminal. The control terminal then reads the cached data to be displayed from the video memory space and displays it, thus completing the task of displaying the data to be displayed on the monitor of the control terminal. Specifically, routing configuration can involve configuring the address routing window. The aforementioned configuration operations can be performed in the operating system bootloader (PMON) of the control terminal.

[0089] In this embodiment of the invention, the designated register of the control terminal is routed according to the spatial address to associate the spatial address with the designated address. If an inconsistency is detected between the designated address and the address in the video memory space, the designated address is further mapped to the address in the video memory space. This ensures that the data to be displayed written by the server at the spatial address corresponding to the first bus domain can be ultimately written to the video memory space of the designated chip, thereby ensuring a certain degree of success rate for data writing operations.

[0090] Optionally, the operation of displaying the data to be displayed on the display screen based on the specified chip may specifically include: outputting the data to be displayed to the display screen based on the display module configured in the specified chip. Specifically, the display module configured in the specified chip may be a display controller, which may operate the video memory based on the address of the video memory space to load the data to be displayed, and render the loaded data to be displayed, and output the data to be displayed to the display screen.

[0091] Furthermore, after outputting the data to be displayed to the display screen, in this embodiment of the invention, it is also possible to detect whether the data to be displayed is successfully displayed on the display screen; if it is successfully displayed on the display screen, a display success command is returned; otherwise, a display failure command is returned.

[0092] Specifically, it can detect whether the image on the display screen is complete. If it is complete, it confirms that the data to be displayed has been successfully displayed. Conversely, it confirms that the data to be displayed has not been successfully displayed. Accordingly, it can return a display success command indicating successful display, or a display failure command indicating unsuccessful display. Upon returning, the display success command / display failure command can be sent to the server, or it can be sent to the server administrator, for example, to the mobile terminal used by the server administrator.

[0093] In this embodiment of the invention, based on the display module configured in the specified chip, the data to be displayed is output and displayed on the display screen. After the display is completed, it is further detected whether the data to be displayed is successfully displayed on the display screen, and a display success command / display failure command is returned accordingly, so that the server can easily know the display result.

[0094] Optionally, the server can be a server-side device, which can be any server platform. The control end can be a Baseboard Management Controller (BMC), and a designated chip can be used as the main chip of the BMC, i.e., a system-on-a-chip (SOC). The BMC can be plugged into the server as a board, and the two are connected by contact, both residing in the same device. Alternatively, it can be located in other devices, such as a computer, and the two are connected via a wired connection. This embodiment of the invention does not impose any limitations on this.

[0095] The following describes an exemplary application scenario related to an embodiment of the present invention. In the server industry, BMC boards are used to manage servers. BMC commands can be used to perform large-scale unattended operations on server clusters, such as remote management, monitoring, installation, and restarting of servers. In this embodiment of the present invention, a designated chip also has display functionality. To avoid resource waste, the designated chip can be used as a BMC board and connected to the server via a PCIe bus, thereby further using the designated chip as a PCIe graphics card for server display.

[0096] Figure 3 This is a connection diagram provided by an embodiment of the present invention, such as... Figure 3 As shown, the server can connect to the BMC (Band Control Center) via a first bus interface and a second bus interface. The BMC can use a 2K0500 chip. When used as a BMC, it needs to connect to the server via the second bus interface. To achieve display functionality (PCIe graphics card function), it can connect to the server via the first bus interface. The DC controller of the BMC can operate the video memory for output display. There can be multiple second bus interfaces, such as I2C bus, LPC bus, etc. Furthermore, when using a specific chip as a graphics card, the server needs to be able to access the video memory space of the specified chip via the PCIe bus. In this embodiment, the server can write the data to be displayed into the video memory space of the specified chip in the BMC based on the space address corresponding to the first bus domain. The display controller inside the specified chip in the BMC can output the data to be displayed from the video memory space to the display, thereby completing the display function.

[0097] Figure 4 This is another connection diagram provided by an embodiment of the present invention, such as... Figure 4 As shown, the server side includes a CPU, which can access the video memory space of the BMC side. Specifically, the CPU inside the server side can access the memory through the PCIe bus between the two. The server side can pre-allocate a portion of the PCIe bus domain to the BMC side from the bus domains available for allocation to all external devices. The BMC side can map the space address corresponding to the PCIe bus domain to the address of the video memory space in the BMC side. This mapping operation can be implemented based on the CPU inside the BMC side, and the PCIe bus can be the first bus mentioned above, and the PCIe bus domain can be the first bus domain mentioned above.

[0098] It should be noted that the server side can be a PCI Express root complex (RC) side, and the BMC side can be an Endpoint Device (EP). The video memory space can be a Dynamic Random Access Memory (DRAM) domain.

[0099] Furthermore, Figure 5 This is a schematic diagram of a processing flow provided by an embodiment of the present invention, such as... Figure 5 As shown, the control terminal can initialize the display controller and allocate video memory space.

[0100] Specifically, the control terminal can determine that the server has successfully allocated the first bus domain to the control terminal if it receives a flag from the server indicating that the first bus domain allocation was successful; otherwise, it can determine that the server has failed to allocate the first bus domain to the control terminal. Furthermore, the control terminal can determine that the video memory space has been successfully allocated if initialization is completed normally and the address of the video memory space is obtained; otherwise, it can determine that the video memory space has not been successfully allocated.

[0101] If the server successfully allocates the first bus domain and video memory space to the control terminal, the address corresponding to the first bus domain is mapped to the address in the video memory space. Then, the data to be displayed in the video memory space is displayed. Conversely, if the server fails to allocate the first bus domain and / or fails to allocate video memory space to the control terminal, a prompt message indicating that the data to be displayed cannot be displayed can be output.

[0102] The server side requires no special configuration; it simply boots normally, undergoing firmware and kernel booting before scanning for external devices. If the controller is successfully identified as an external device, it allocates the first bus domain to it. The controller can be ported and adapted based on existing firmware and kernel. After firmware boot initialization and kernel booting into the system, the controller initializes the display controller and allocates video memory.

[0103] In this embodiment, the designated chip is further used as a graphics card for server display. This maximizes the functionality of the designated chip, expands its application scenarios, and allows it to play a greater role. Simultaneously, using the designated chip as a graphics card reduces the number of graphics cards required, thus saving costs.

[0104] It should be noted that, in this embodiment of the invention, the server may write the data to be displayed into the allocated first bus domain, and then the control terminal may actively read and write it into the video memory space to achieve display.

[0105] Figure 6 This is a structural block diagram of a display control device provided in an embodiment of the present invention, such as... Figure 6 As shown, the device may include:
